9. ce15-9 Q4: How Does a Work-Breakdown Structure Drive Project Management? Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall Work-Breakdown Structure (WBS)WBS –Hierarchy of tasks –Tasks end with deliverables  Documents, designs, prototypes, data models, database designs, working data entry screens, etc. –Identifies task dependencies –Estimate task duration, cost and labor needed –Created with project management software, such as Microsoft Project

13. ce15-13 Biggest challenge is scheduling –How long does it take to:  Develop a large data model?  Adapt data model to user satisfaction?  Develop a computer program? –Scheduling errors accumulate (e.g., snowball) –Difficult to do credible planning –Every task may be on critical path Q5: What Is the Biggest Challenge for Planning a Large-Scale Systems Development Project? Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall

14. ce15-14 Three Approaches to This Challenge Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall 1.Avoid major schedule risks and license software from vendors. 2.Admit impossibility of systems development scheduling and plan accordingly. 3.Attempt to schedule development project despite difficulties.

15. ce15-15 Estimation Techniques Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall Estimate using past projects as a guide. Estimate lines of code to be written. Use industry or company averages to estimate time required. Estimate function points in a program, determine number of lines of code, and estimate schedules.

16. ce15-16 Coordination Diseconomies of scale Configuration control Unexpected events Maintaining team morale over time Q6:What Are Biggest Challenges for Managing a Systems Development Project? Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall

17. ce15-17 Taking responsibility for requirements Systems built to support business functions, to help organization achieve goals and objectives Managing requirements is critical Ensure requirements are complete and accurate Q7: What Is the Single Most Important Task for Users on a Systems Development Project? Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall

18. ce15-18 Role of Users Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall Users cannot be passive Responsible for ensuring complete and accurate requirements Responsible for managing requirements changes, avoiding requirements creep Define testable conditions for functions and features Evaluate data models, provide test data and sample scenarios Conduct user testing (beta testing) Final approval of system
